农村饮用水重金属健康风险评价

Health risk assessment of heavy metals in rural drinking water

为研究农村饮用水中重金属对人体的健康危害,对某地区浅层地下水中的重金属进行了监测分析后,对7种重金属所引起的健康风险进行了评价。结果表明,该区域地下水中重金属的总健康风险与致癌健康风险均接近国际辐射防护委员会(ICRP)推荐的最大可接受值,非致癌健康风险基本属于可忽略水平,其中,需要优先控制管理As和Cd两种重金属元素。

In order to analyze the potential risk to human beings＇ health caused by heavy metals in groundwater,we have monitored the shallow groundwater of the area we study and assessed the health risk of seven kinds of heavy metals.The results show that both the health risk and the carcinogenic risk there exceed the acceptable level advanced by ICRP,and the non-carcinogenic risk can be more or less ignored.Besides,the elements of As and Cd must be managed first.
